Answer:
The related multiplication expression is 
.
Solution:
Given expression is .
We can write 5 as a fraction with denominator 1.
Using the fraction rule 
,
Now multiply the fractions using the rule 
,
Let us multiply the numbers in the numerator and denominator separately, we get
Hence the related multiplication expression is .
If wrong i apologize but for that equation i got the answer K=117

.
Explanation:
By definition, the angles of a rectangle are right. Therefore, drawing a diagonal creates two congruent right triangles. The diagonal of the rectangle is the hypotenuse of the right triangle. The sides of the rectangle are the legs of the right triangle. We can use the Pythagorean Theorem to find the unknown side of the right triangle, which is also the unknown length of the rectangle.
Recall that the Pythagorean Theorem states that the sun of the squares of the legs of a right triangle is equal to the square of the hypotenuse.

Since the length of the side is a measured distance, the negative root is not a reasonable result. So the length of the rectangle is
12
cm.
The area of a rectangle is given by multiplying the width by the length.
